Fig. 9
Total UV flux as computed with Eq. (7) (violet) and the contributions to this total by Lyα (red), Lyβ (cyan), and two-photon continuum (blue) at the shock front (z = 0) for shocks with velocities VS = 25–60 km s−1 and preshock densities nH = 104 cm−3. The dashed horizontal line represents the standard interstellar radiation field.
